TĂNG TRƯỞNG THỂ CHẤT TỪ 0-10 TUỔI CỦA TRẺ SINH ĐỦ THÁNG TẠI TỈNH THÁI NGUYÊN

Abstract

Objective: To describe the physical growth characteristics of full-term children aged 0 to 10 years in Thai Nguyen province. Materials and Methods: A prospective cohort study was conducted on 703 children born in 2012–2013 across 20 communes in four districts representing both mountainous and midland areas of the province. Anthropometric measurements, including length/height and weight, were collected at birth, 3 months, 6 months, 12 months, 18 months, 24 months, 6 years, and 10 years of age. Data were analyzed using Stata 17.0 software, and independent t-tests were applied. Results: The average length increased from 49,19±3,06 cm at birth to 134,97±6,53 cm at 10 years of age. Growth velocity was highest in the first year (23,58 cm), then gradually declined in subsequent stages. Weight increased from 3,17±0,36 kg to 29,97±7,02 kg at 10 years, with the fastest gain occurring during the first 6 months (702–812 grams/month), followed by a decline. Boys were generally taller and heavier than girls at most time points; however, by the age of 10, girls had a significantly higher average height than boys (135,58±7,19 cm vs. 134,37±5,74 cm; p=0,014). Conclusion: Children born full-term in Thai Nguyen exhibited stable physical growth patterns but remained below international standards. Early nutritional and health interventions are necessary to improve child growth and stature in the region.
